I came across a paper that said that they Trotterized a CNOT gate into 4 blocks of CU gates where the CU gate parameters are specified. This was all done on Qiskit. How does this Trotterization actually work? How do I perform it mathematically? Where is an actual proof that this Trotterization is equivalent to the CNOT gate itself. I have attached an image of the Trotterized CNOT gate if it is of any help. Thanks!
